I am trying to make a custom external loader for a qspi nor flash. the erase sector and write operation is success but after I tried the read operation the operation is fail the device is disconnected and showing this message

I have tried to run a program like this demo project , the program is working normally and I can read the data . buat after I comment the write section :

if (CSP_QSPI_WriteMemory(buffer_test, var * MEMORY_SECTOR_SIZE,
				sizeof(buffer_test)) != HAL_OK) {
			Error_Handler();
}

and read the memorry, the device is disonnected and I have restart the device if I want to connect again. any one know why ?, thank you.

Exit path for Write() should enable Memory Mapped Mode

Will need to drop out of Memory Mapped mode to erase, write and wait for completion, and then switch back to Memory Mapped mode for the tools to Read/Verify the content.

Hello , thank you for the reply. I am using HAL_XSPI_Abort(&hospi1); to exit from memory mapped mode so the code I am running look like this

	if (CSP_QUADSPI_Init() != HAL_OK) {
		Error_Handler();
	}
	if (CSP_QSPI_EnableMemoryMappedMode() != HAL_OK) {
		Error_Handler();
	}
	HAL_XSPI_Abort(&hospi1);

the disconnect problem is clear but of course I can't see the data with read memorry fiture on stm32cubeide. if I comment the HAL_XSPI_Abort(&hospi1);, the disconnect problem occurs again after I use the read memory fiture on stm32cubeide.
